最新版本的 wxPython 不支持 wxversion 模块。相反，信息以 wx.version 形式提供。
有没有什么建议可以解决这个问题？谢谢！
我的环境是 Ubuntu 20.04 LTS、pyenv、python 3.8.3、python 2.7.18、wxPython 4.1.0
$ apt-cache policy playonlinux

安装的Python 3.8.3配置有wxPython 4.1.0

因此，playonlinux 命令失败并出现以下错误：

注意：对于那些在 Ubuntu 20.04 LTS 上安装 wxPython 遇到困难的人由于 GTK+ 错误*** Could not run GTK+ test program, checking why...
尝试这个命令（在这里找到：https://wxpython.org/pages/downloads/）
pip install -U -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-20.04 wxPython
更多背景信息另请参阅：https://discuss.wxpython.org/t/where-to-obtain-wxversion-py/28752
playonlinux 最初安装如下，但使用 Ubuntu 20.04 LTS 上的标准存储库重新安装（我从 19.10 升级）：
我正在运行的 playonlinux 版本是从这里下载的 Ubuntu 18.04（Bionic 版本）：https://www.playonlinux.com/en/download.html
For the Bionic version
Type the following commands:
wget -q "http://deb.playonlinux.com/public.gpg" -O- | sudo apt-key add -
sudo wget http://deb.playonlinux.com/playonlinux_bionic.list -O /etc/apt/sources.list.d/playonlinux.list
sudo apt-get update
sudo apt-get install playonlinux
也许 playonlinux 已被 flatpak 版本取代了？
查看 Github 链接https://www.playonlinux.com带你到https://github.com/PhoenicisOrg/这表明也许解决方案是迁移到 flatpak 版本：

简短回答：问题与以下方面有关：pyenv，请确保system全局配置中是首选：pyenv global system或者使用 为当前 shell 设置 python 版本pyenv shell system。如果使用，global则只需设置一次。
简短解释：用于pyenv global system (2nd) (3rd)...确保 playonlinux 找到正确的 python；其中 (2nd) 和 (3rd) 是您所安装的解释器的 pyenv 版本号。
详细解释：在阅读了@N0bert 的非常有用的帖子后，我发现我的问题是pyenv 相关。
具体来说，我可以通过使用pyenv global命令并system首先执行如下操作来解决我的问题（注意：您执行的命令取决于您安装的 python 版本）：
pyenv global system 3.8.3 2.7.18 anaconda3-2019.10
为了进一步调查该问题，我查看了以下文件：
/usr/share/playonlinux/bash/find_python/usr/share/playonlinux/python/check_python.py
我复制了这些文件，以便更好地理解错误。结果wxversion错误确实具有误导性，真正的问题是找到正确的 python shell 来运行。playonlinux取决于系统 python。
最初我以为运行pyenv local system可以解决问题，但是由于 pyenv 的工作方式，事实并非如此。
为了确保/usr/share/playonlinux/bash/find_python解析为系统安装的python，您必须确保将其pyenv global设置system为首选。
非常感谢@N0rbert！！

您只需从官方存储库安装最新的 PlayOnLinux 4.3.4 即可
sudo add-apt-repository multiverse
sudo apt-get install --reinstall playonlinux=4.3.4-1ubuntu1
它将依赖于 Python 2，因为它旨在。
